Python HDMI Matrix control library for AVGear and possibly other HDMI matrix controllers

AVGear HDMI Matrix Python Library

Python library to control AVGear HDMI Matrix switches (tested with TMX44PRO AVK, may work with others). Both synchronous and asynchronous APIs are provided. Contributions for other models are welcome!

This is used for the AVGear Matrix integration for homeassistant.

Inspired by pyblackbird.

Features

• TCP/IP control: Communicate with the matrix over the network
• Sync & Async APIs: Use either blocking or asyncio-based methods
• Device info: Query device name, type, version, and status
• Routing control: Route HDMI inputs to outputs programmatically
• Video status parsing: Parse and display current input/output routing
• Context manager support: Use with with or async with for auto-connect/disconnect
• Logging: Built-in debug/info/error logging

Installation

Clone the repo and install dependencies (if any):

git clone https://github.com/marklynch/hdmimatrix.git
cd hdmimatrix
# Optionally: pip install .

Usage

Synchronous Example

from hdmimatrix import HDMIMatrix

matrix = HDMIMatrix("192.168.0.178", 4001)
with matrix:
    print(matrix.get_device_name())
    print(matrix.get_device_status())
    matrix.route_input_to_output(1, 1)

Asynchronous Example

import asyncio
from hdmimatrix import AsyncHDMIMatrix

async def main():
    matrix = AsyncHDMIMatrix("192.168.0.178", 4001)
    async with matrix:
        print(await matrix.get_device_name())
        print(await matrix.get_device_status())
        await matrix.route_input_to_output(1, 1)

asyncio.run(main())

Video Status Parsing

with matrix:
    routing = matrix.get_video_status_parsed()
    print(routing)  # {1: 1, 2: 3, 3: 2, 4: 4}

    # Show which input is connected to each output
    for output, input_num in sorted(routing.items()):
        print(f"  Output {output} <- Input {input_num}")

Power and Output Control

with matrix:
    matrix.power_on()
    matrix.power_off()

    # Enable/disable individual outputs
    matrix.output_on(2)
    matrix.output_off(2)

API Overview

• HDMIMatrix (sync) and AsyncHDMIMatrix (async) classes
• Connection:
  • connect()
  • disconnect()
  • Context manager support (with / async with)
• Info:
  • is_powered_on()
  • get_device_name()
  • get_device_status()
  • get_device_type()
  • get_device_version()
  • get_video_status()
  • get_video_status_parsed()
  • get_hdbt_power_status()
  • get_input_status()
  • get_output_status()
  • get_hdcp_status()
  • get_downscaling_status()
• Control:
  • power_on()
  • power_off()
  • route_input_to_output(input, output)
  • output_on(output)
  • output_off(output)

Development

Install with dev dependencies:

pip install -e ".[dev]"
